HOVARD HUNT, OF MONROE, WISCONSIN.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 394,365, dated December 11, 1888.

Application tiled November 16, 1886. Renewed August 25, 1888. Serial No. 283,793. (No model.)

I do declare the following to be a t'ull, clear, t

and exact description ot the invention, such as will enable others skilled in the art to i which 1t appertains to make and use the saine, reference being' had to the accompanying drawings, and to letters or figures of reterence marked thereon, which t'orm a part of this specification.

Figure l ot' the drawings is a representation of a bottom plan view. Fig. is a vet'- tical longitudinal section on the line 1; 11,lt`ig. l. Fig. 3 is a detail view, partly in section, of one ot' the brake-shoes.

My invention relates to automatic wagonbrakes; and it consists in the construction and novel combination ot' parts, as hereinat'ter described and claimed.

Referring by letter to the accompanying drawings, A designates the running-gear ot' a wagon, which may be otl any ordinary construction, except as to novel features de,- scribed lfurther on.

Bis the front axle, C the rear axle, and D the reach.

E E are the front hounds, F the hind hounds, and (if H the front wheels ot' the running-gear.

I is the tongue or pole, which is slotted transversely through at K L M to receive the transverse bolt-rod N, by which it is held in place between the extensions or arms of the front hounds.

P is a spiral or Coil spring, which is connected at one end to the tongue or pole I by a casting, Q, or in any other suitable manner, and at the other end said spiral or coil spring is connected to the front bolster or sandboard, R, and serves to assist in supporting' the weight ot' the pole and keeping it from the horses necks.

At their rear ends the arms of the t'ront hounds are connected by a transverse bar, S, to the lower face of which the brake-levers T U are fulcrumed, the tulcrum-points being near the outer ends ot' said transverse bar S. Loops V V, connected to the transverse bar S, surround the brake-levers T U near their inner ends and limit the movement downl l l ward ol' said brake-levers.` At their outer ends the brake-levers T U are provided with brake-shoes Y V', which are designed to brake the t'rout wheels of the wagon. The brake-shoes Y V are provided on their convex edges with curved tangential metal scrapers lV, which, when the brakes are applied, engagc the tires of the t'ront wheels and scrape the mud therefrom and prevent it from reaching the brake-shoes. At their inner ends the brake-levers are connected to the sliding tongue or pole bya forked rod, X. 'hen the team draws upon the tongue,

i the brakes are thrown olf the t'ront wheels; y but when descending an incline the weight of the wagon, pressing forward on the tongue, applies the brakes, and the greater the load on the wag'on the greater will be the pressure on the brakes. The coil-spring also assists the horses in applying the brakes, for as soon as the horses cease to draw upon the tongue the spring ret'racts it and ot' itself will apply the brakes with considerable force.

llaving described this invention, what I claim, and desire to secure by Letters Patent, is-

l. 'l`l1e combina-tion,with the running-gear ot' a wagon provided with the sliding tongue and the transverse bar secured to the reach and front hounds in rear ot' the front wheels, of the brakelevers, the brake-shoes, the spring' connecting the sliding' tongue to the front bolster, and the forked rod connecting' the brake-levers and sliding' tongue, substantially as specified.

2. l'he combination, with the brake-levers and the sliding tongue connected therewith, ot' the spring connecting the sliding tongue tothe running-gem' of the wagon, whereby when thc drat't on the tongue is relieved the brake is applied, substantially as specitied.

25. The combination, with the running-gear ot' a wagon, ot' the sliding tongue and brakelevers and connections, the brake-shoes, and the curved tangential scrapers lV, secured to the edges ot' said shoes, substantially specitied.

ln testimony whereof l atiix my signature in presence ot' two witnesses.
